Specification of Letters Patent.

Patented Aug. 29, IQIH.

of Ohio, have invented a new and useful Improvement in Suction-Nozzle Brackets, of which the following is a specification, the principle of theinvention being hereln explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

This invention has more particular reference to a bracket intended to support one or more suction nozzles adjacent a sheet conveyer which as exemplified is the'reclprocal cylindrical surface of a printing press.

The object is to provide a bracket which may be quickly attached and as readily removed from certain standard parts of a printing press, which parts in the illustrated type of press rise and fall in unison with tile n this manner any predetermined adjustment of the suction device with respect to the surface of a sheet which is being carried upon the cylinder may be maintained.

Adverting to the drawings: Figure I s a plan view of a portion of one end of a printing press involving a cylindrical sheet conveyer. Fig. II is a section on line II II of Fig. I. Fig. III is a section on l1ne III-III of Fig. II. Fig. IV is a section on line IVIV of Fig. III. Fig. V is a section on line VV of Fig. II. Fig. VI is a section on line VIVI of Fig. II. Fig. VII is a partial top view showing the application of my invention along the cylinder of a tworevolution type of press. Fig. VIII 1s a partial end view showing the manner in which the cylinder sheet conveyor is mount ed for up and down movement on the frame.

A portion only of the frame 1 is shown in Figs. I and III. Inasmuch as the manner in which the cylinder 2 is mounted upon a press of this type so as to rise and fall at determined intervals, is old and well known to the art, the identifying reference just made is all that is required. Extending across the press in front of the cylinder 2 is a bar 3 and higher up three additional bars are supported in step-like arrangement upon a pair of extensions 4. The uppermost or tape bar 5 is rotatably mounted. The middle or stripper-finger bar 6 is also movably mounted. The lower or fly-rest bar 7 is stationary. I choose to attach the bracket to the bars 5 and 7 as is clearly shown in Figs. I and II. The bracket comprising the subject matter of this invention is composed of a number of separable parts certain of which are adjusted moreover with respect to certain other parts, and two complete brackets will ordinarily be required at opposite ends of the press. For the purpose of simplifying the description, but one bracket construction will be described in detail and hence with few exceptions the singular number employed.

A primary part 8 involves an upwardly extending arm 9 provided with a bearing 10 for the tape bar 5. Adjacent the bearing 10, the arm 9 is flanged at 11 such that a cap 12 may be secured thereto by means .of cap-screws 13. The part 8 also involves a laterally projecting arm 14 provided below with a semicircular recess 15 in which the fly-rest bar. 7 is supported. A cap 16 complementarily recessed is adapted to overlie the fly-rest bar 7 and is secured to the arml i by means of cap-screws 17. It is apparent therefore, that the primary part 8 is supported in front of the cylinder 2' without interference with the action of the stripper finger bar 6 and so as to permit the rotation in a suitable bushing of the tape bar 5. It is from the primary part8 that such parts as will be described hereinafter are sus pended. i

The part 8 furthermore comprises a downwardly extending arm 18 provided with a pair of forwardly projecting dowel pins 19. Fitted to the arm 18 with openings correspondingly spaced as such dowel pins, is a secondary part 20 and this may be fixedly secured to the arm 18 throughthe agency of a thumb-screw 21. The secondarypart 20 is fashioned below as a transversally extending guide 22 recessed underneath and from the inner end 23 as is best seen in Fig. VI. The outer end 24: is fashioned as a depending projection and is provided with a horizontally extending screwthreaded opening. A slide 25 corresponding above in exterior contour with the recess 23 is adapted for sliding movement therein, as is also apparent from the inspection of Figs. II and VI. The slide 25 is similarly provided on its outer end'with a depending projection 26 having an opening in line with the screw llllh ltd threaded .opening in projection 24:. A scr *w 11m 'from the cylinder 2. Inwardly,

' ings opposed to said conveyer,

27 provided on its outer end with a knurled head 28 extends through the two alined openings in the projections 24 and 26 and has pinned thereto on its other and inner end a collar 29. A look nut 30 is also shown.

7 From the construction just described. and as shall be readily understood, the movement of the screw 27 in either direction serves to actuate the slide 25 in the same direction,

and thereby adjust the same toward'or away thatjis toward the cylinder 2 a lower broadened portion 3l of the slide 25 is fashioned with a slot 32 adapted to be occupied'by one angu lar extension of a standard angle bar 33. The bar 33 is secured in a slot 32 by means of cap-screws 34 shown in Figs. II and V. Such bar 33 is intended to extend across the entire front of the cylinder 2 and to directly support, in the exemplification disclosed, 'a plurality of nozzles 35 secured thereto at 36. These nozzles carry above brushes 37 and are detachably coupled at 38 to branches 39 of a suitable manifold and suction fan neither of which is shown.

I would direct attention especially to the following: fact that it is supported upon so much of the frame of the press as moves up and ,down with the cylinder 2, movesin unison with the latter and therefore when once properly adjusted the, intake openings of the nozzles are consistently spaced the same distance from the surface of the sheet which 1s being carried around upon the surface of the cylinder. .That the suction contrivance may be readily removed from the press as a whole by simply withdrawing the thumb screws 21. That the nozzles proper after independently removed by loosening and withdrawingthe angle bar 33 from the slide 25. That the adjustment of all of the nozzles relative to the cylinder may be acbeing uncoupled from the manifold may be .complished by the mere manipulation of the two screws 27 at opposite ends of the press.

A device of the character described comprising the combination with a movable support, a sheet conveyer revolubly mounted on, said support, a member carried by said support and extending across said conveyer, a plurality of suction nozzles alined across said member andhaving intake openand a suction manifold connected to said nozzle outlets.
